Better scenery_packs.ini handling

• Overlay packages go above the photo packages. If your scenery packages folder has a package with "Overlays" in its name, OrthoStreamXP now places it first among its own packages in scenery_packs.ini. The overlays then draw on top of the photo scenery. Airports and other custom scenery above OrthoStreamXP's packages stay where they are.
• No more duplicate entries. If scenery_packs.ini already lists a package with the same name as one OrthoStreamXP mounts, the old line is removed and replaced with OrthoStreamXP's entry. This covers packages you had added from their original location. Each package now loads once, from OrthoStreamXP.
  • Only exact folder names match. Packages whose names merely start the same way are left untouched.
  • A package you had disabled stays disabled.
  • Your previous file is still saved as scenery_packs.ini.bak before any change.
